Configuring System and Network Settings

System settings appears to be a tab designed to ensure data transmission parameters configuration. Default values and range of values for each parameter are indicated in table below.

Parameter Description Default value Value options
Data slice formation period Data Slices periodicity registration in the log 3600 sec (once an hour) 60 – 86400 sec
Disable sporadic data transmission Disables data transmission
initiated by the Data Logger. The data archive is transmitted only on request from the server 		Sporadic data transmission enabled Enabled/
Disabled
Input trigger level automatic detection Automatic detection
of input response states by resistance:
1 - 15 kOhM – 4 states (NAMUR circuit)
Short circuit/break – 2 states 		Enabled Enabled/
Disabled
Active SIM card selection Setting up SIM cards operating mode Auto
(see 1.13, SIM cards operation) 		SIM1/SIM2/Auto
GPRS class selection GPRS class selection:
class8, class10 or Auto (class8/10/12) 		class 8 class 8/class 10/Auto

Network registration standby time Maximum time to register in a network
using both SIM cards
(in case both cards are installed). If communication session fails, the next attempt to register in the network will occur after 1 hour, then after 2, 4, 8, 24 hours, and then every 24 hours. 		120 seconds

Enable SIM card activity control

The option works only, if in the Active SIM card selection parameter Auto is set.

Enabling the option to monitor modem activity on SIM cards.

On an inactive SIM, a periodic connection to the server will be initiated in order to prevent SIM card disconnecting for non-use. DTU will establish the connection from this card after the end of the period specified in the Maximum SIM card inactivity period line.

If the device does not establish the connection after the end of the period specified in the Maximum SIM card inactivity period, the event "The period of no connection on SIMX exceeded" will be generated, and then device will repeat connection attempts in accordance with the parameter Number of repeated connections after inactivity

Disabled
